In the general case, it's harder to resume systems using framebuffers than systems that don't. The contortions that are necessary for non-fb systems tend to break fb systems (you end up with userspace and the kernel both trying to get the graphics hardware back into a sane state), so in an ideal world resume would work without any framebuffer support. -- Matthew Garrett | mjg59-chiark.mail.linux-rutgers.kernel@srcf.ucam.org
